RATIONALE: Radiation therapy uses high-energy x rays to kill tumor cells. Radiation therapy may cause skin reactions when patients are exposed to high-energy x rays. Studying the genetic pattern of patients before and after radiation therapy may help doctors prevent toxicity and plan the best treatment.
PURPOSE: This clinical trial studies genetic susceptibility to radiation-induced skin reactions in racial/ethnic groups of patients with breast cancer.
OBJECTIVES:
OUTLINE: This is a multicenter study. Patients are stratified according to race/ethnicity (Whites* vs Black/African Americans vs Hispanic/Latinos vs Asians/Native Hawaiians/Pacific Islanders vs American Indians/Alaskan Natives). NOTE: *This stratum is closed as of April 25, 2012.
Patients undergo adjuvant radiotherapy after breast-conserving surgery.
Blood and urine samples are collected at baseline and last day of radiotherapy for genotyping, DNA damage, cell cycle assays, urine cotinine, inflammatory immune response biomarkers, and tumor-killing activity by BeadArray System, Comet assay, flow cytometry-based assay, Cell-Cycle G2 Delay Assay, Oxygen Radical Absorbance Capacity (ORAC) assay, and ELISA.
Patients are assessed for acute toxicity by research staff using the ONS Criteria for Radiation-Induced Acute Skin Toxicity at baseline, week 3, and at 1 and 2 months after radiotherapy. Patients are also assessed for chronic toxicity by research staff using the Chronic skin toxicity questionnaire (RTOG SOMA Criteria for RT- Induced Breast/Chest Wall Late Skin Toxicity) at 6 and 12 months after completion of radiotherapy. Photographs of the breast, chest wall, and contralateral breast are also taken at baseline, week 3, last day of radiotherapy, and at 1, 2, 6, and 12 months after completion of radiotherapy.
Patients complete the Breast Cancer Risk Study Questionnaire, the Functional Assessment of Cancer Therapy Breast (FACT-B), the Modified Skindex, and the B39 Quality-of-Life (QOL) Questionnaire at baseline, last day of radiotherapy, and at 1, 2, 6, and 12 months after radiotherapy.
14,825 studies on the registry are indexed under Breast Neoplasms; 3,319 are open to participants now.
This study's enrollment of 1,000 is above the median of 184 across 3,235 observational studies indexed under Breast Neoplasms.

DISEASE CHARACTERISTICS:
Female patients newly diagnosed with breast carcinoma including ductal carcinoma in situ (DCIS)
PATIENT CHARACTERISTICS:
PRIOR CONCURRENT THERAPY:
No patients who underwent breast reconstruction following mastectomy
Patients may not be concurrently enrolled in a protocol that involves treatment of the skin, i.e., applying lotions/moisturizers
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

Occurrence of RT-induced early adverse skin reaction (EASR)
The primary endpoint is RT-related skin reactions which for consistency and clarity across the study we will use the term "Early Adverse Skin Reaction" (EASR). Skin reactions will be assessed at 4 time points from the start of radiotherapy through 2 months of the post radiotherapy follow-up period. The Modified ONS Criteria for Radiation-Induced Acute Skin Toxicity will be used for classification of EASRs related to the skin. The primary outcome variable will be the occurrence (or not) of RT-induced EASR defined as a grade 4 or higher toxicity (based on the ONS criteria) during the 2 months of the follow-up period of the study.
Time frame: 2 months
Quality of life as measured by FACT-B
Quality of life will be assessed using the FACT-B, a modification of the Skindex-16, and a modified version of the NSABP B39 Quality of Life metric.
Time frame: 12 months
Ran from Sep 2011 to primary completion in Aug 2014, 35 months.
Of 1,191 non-industry observational studies under Breast Neoplasms, half reached primary completion within 58 months of starting (the median), counting those still running; a quarter within 25 and three quarters within 139. This study's 35 months is below that.
Counting every sponsor, half of 1,380 studies reached it within 55 months; a quarter within 25 and three quarters within 126.
